The Library of the German Bundestag primarily serves the German Parliament.

The Bundestag Library began its work in 1949 with a stock of 1,000 volumes taken over from the Parliamentary Council. Today, with over 1.3 million volumes, it has both an extensive collection of specialist literature and special collections of parliamentary materials and official publications. German official publications issued by the Federation, the Länder or federal states, and the communes are received by legal deposit. The Bundestag Library is also a deposit library for international and supranational organizations, i.e. these organizations supply the Library with all their publications on a regular basis. Finally, the Library of the German Bundestag is one of the Federation's three official training libraries for librarians in the higher, higher intermediate and intermediate career ranges.
